Subject: [patch 75/86] arm: nommu: use pgtable-nopud instead of 4level-fixup
Date: Wed, 04 Dec 2019 16:53:48 -0800 [thread overview]
Message-ID: <20191205005348.YkDiV-f2Y%akpm@linux-foundation.org> (raw)
In-Reply-To: <20191204164858.fe4ed8886e34ad9f3b34ea00@linux-foundation.org>
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: arm: nommu: use pgtable-nopud instead of 4level-fixup
The generic nommu implementation of page table manipulation takes care of
folding of the upper levels and does not require fixups.
Simply replace of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h.
